1. Safety PrecautionsTo prevent personal injury, injury to others, or damage to property, read these safety precautions carefully before use.

• Do not disassemble, modify or repair. There are no user serviceable parts inside the freezer unit.*

• Do not immerse in water or pour water on the unit.*

• Warning: Unauthorized modification to the cabinet, controls or free-piston Stirling engine is prohibited and will void all warranty provisions.

• Do not put ice or liquid water directly in the freezer box, always use suitable containers.

• Do not use glass containers when the contents might freeze and break.

• Do not store flammable items such as gasoline, thinner or solvents in the freezer. The freezer is NOT rated as an explosion-proof freezer.

• Do not use hard and/or sharp objects, such as knives, screwdrivers, etc. to remove any frost or ice which has accumulated on the inside of the freezer. The inside panels are heat exchangers and can be damaged.

• Do not cut, change or modify the power cable.*

• When removing the plug, hold onto the plug and not the cord.

• Do not block the air intake or air discharge vents.

• Do not drop, throw or abuse the freezer.*

• Do not operate under extreme environmental conditions, such as in a car trunk, in very high humidity environments, in rain or other severe weather.*

• Do not use solvents to clean the control panel or the outside or inside of the freezer.

• An ultra-low temperature freezer is qualitatively different than a home freezer. At -86ºC frostbite can occur instantly.

• The user should establish and follow a protocol for safe ultra-low temperature operat-ing procedures. This should include (but not limited to): — Never handle samples or freezer accessories with bare hands. — Do not use gloves which become brittle at ultra-low temperatures. — Nitrile and latex gloves are inadequate.


• Permeable gloves are dangerous because ultra-low temperature materials can contact skin and cause damage. — Be especially careful that materials at ultra-low temperature are not spilled onto skin or clothing. — Use only sample containers that have been approved or tested for ultra-low temperature use. — Some plastics shatter at ultra-low temperatures. Avoid splinter hazards. — Biological and chemical hazards are still hazardous at ultra-low temperature. Always wear proper protective equipment and follow appropriate isolation protocols. — Many types of labels will fall off and/or break at ultra-low temperature. Some types of ink which stick to glass and/or plastic at room temperature lose adhesion at ultra-low temperature.

• In addition to the ultra-low temperature hazards above, there are also physical hazards to consider: — Be cautious when closing the lid to avoid a pinching hazard. — Be careful when loading the box with heavy items. — Always use the handles to carry the freezer.

*Doing so will void the warranty.

1. Safety Precautions



2. Unpacking and Set-Up1. Remove the freezer and all accessories from the box. Carefully inspect

the freezer and all accessories for any shipping damage.

2. Check the packing list to verify that the shipment is complete.

3. Place the freezer on a level surface.

4. Make sure that the air inlets and outlets are not blocked.

5. Connect to a power source. The freezer can be used with either the AC Power Supply for lab, home or office use, or the DC Power Cord for mobile use.

A. To use the AC Power Supply:

i. During setup, identify the service power and plug configuration available and then locate the appropriate line cord for the service type you will be using. ii. If the appropriate line cord is not currently installed, simply unplug the line cord from the unit and then plug the appropriate line cord in its place. iii. Plug the other end of the line cord into the power source and then attempt to power on the Shuttle.

B. To use the DC Power Cord in a motor vehicle:

i. Make sure the freezer remains level. Exceeding an angle of 12 degrees may cause loss of cooling. ii. Plug the DC Power Cord into a 12V outlet that is rated at 20 amps. (NOTE: Not for use with 24 volt automotive systems) (20 A DC REQUIREMENT: Consult your automotive specialist if your vehicle lacks 20 A rated 12V outlets.) iii. Plug the opposite end into the ULT-25.


6. Notes on operation in a vehicle.

A. The ULT-25 will operate on battery power for a limited time before the battery is drained and the motor vehicle cannot be started. This time will vary from vehicle to vehicle but is generally only a few hours.

B. The engine should be running to prevent accidental total discharge of the battery.

C. The power to 12V outlets in some vehicles may be interrupted during engine starting. This will cause a sudden stop of the cooling unit which may produce a sound that is different than when turning off the ULT-25 by using the Off button. This is normal and will not damage the cooling engine. The cooling engine will restart automatically once power resumes.

D. 20 A DC REQUIREMENT: Please note that 20 A DC service is required for proper functioning of the ULT-25 in a motor vehicle. Some vehicles may not be equipped with 20 A DC service. Consult your automotive specialist to verify the level of DC service installed in your vehicle.

E. Do not operate the ULT-25 in an unattended vehicle. This may lead to overheating if left in the sun and subsequent damage to stored contents.

7. Disconnecting from power.

A. Turn off the freezer (see page 14).

i. The seven-segment display will show the word “OFF” while the ULT-25 Shuttle turns off. ii. Unplug the freezer after the word “OFF” disappears and the display goes dark. iii. If you unplug the freezer while it is on, you will hear a sudden noise when the free-piston Stirling engine shuts off. Power outages will also cause the same noise. This noise (sort of a “bonk”) is not indicative of damage.

3. Features



4. OperationImportant changes to the freezer settings require sustained button pushes. This helps prevent accidental changes to the settings during transportation. Some sequences require a three-second button press and hold while other sequences require a five-second button press and hold.

For example, Turning the freezer ON requires a three-second press and hold (two beeps). Turning the freezer OFF requires a five-second press and hold (three beeps).

The default display is the chamber temperature. Other displays such as Setpoint, Alarm Postpone, etc., are marked with a letter such as S (Setpoint), h (Alarm Post-pone), etc. These secondary displays revert to the default display after approximately eight seconds of button inactivity.

4.1 – How to Turn the Freezer On/Off4.1.1 – To Turn the Freezer On

• Press and hold the I/O button for two beeps (~three seconds).

• The freezer will display a greeting message, and then display the chamber temperature.

4.1.2 – To Turn the Freezer Off

• Press and hold the I/O button for three beeps (~five seconds).

• The freezer will display “OFF” for 10 seconds, and then go dark.

4.2 – Changing the Set Temperature4.2.1 – To See the Current Set Temperature

• Press the Set Temp button briefly.

• The current set temperature will be displayed with the letter S ##. — After eight seconds of inactivity the display will revert to the current temperature.

4.2.2 – Change the Setpoint to a New Value

• There two ways to change the Setpoint. — Manually adjusting the temperature using / . — Using one of three adjustable Preset Buttons.

• Adjusting the Setpoint manually. — Because of the importance of the Setpoint Temperature, changing the Setpoint requires a “two-button procedure”. This means: Method A - either holding the Set Temp button while simultaneously pressing. / — OR Method B - holding down Set Temp until the Set Temp LED glows and then pressing / . (Methods A and B achieve the same effect. The user can use whichever method they prefer.)


• To change the set Setpoint by Method A — Press and hold the Set Temp button and then push the / buttons (do not release the Set Temp button).

– The Setpoint temperature will appear with the prefix S in the seven-segment display.

– When the / buttons are first pushed the Setpoint will change by 1ºC at first.

– If the / buttons are held for five seconds the step size will increase/decrease by 5ºC.

– If the / buttons are briefly released (less than a half second) while continuing to hold down the Set Temp button the increment/decrement size will return to 1ºC.

– Release all buttons once the desired Setpoint is achieved. The display will return to chamber temperature after about eight seconds.

• To change the Setpoint by Method B — Press and hold the Set Temp button until the Set Temp LED glows.

– The Setpoint temperature will appear with the letter S in the first seven-segment display.

— The / buttons can be used to change the Setpoint.

– When the / buttons are first pushed the Setpoint will change by 1ºC at first.

– If the / buttons are held for five seconds the step size will increase to 5ºC.

– Briefly release (a half second) the / buttons while continuing to hold down the SET button the increment/decrement size will return to 1ºC.

– Release the / buttons once the desired Setpoint is achieved.

— Press the Set Temp button briefly (less than one second) to turn off the Set Temp LED. The display will return to chamber temperature.

4. Operation



4.3 – Using Preset Temperatures• The three buttons labeled 1, 2 and 3 can be used to quickly change the Setpoint to

frequently used values. When shipped the Presets are set to -86ºC, -40ºC, and -20ºC.

• To choose one of the preset temperatures:

— Press and hold the Set Temp button until the Set Temp LED glows.

— Push one of the Preset Temperature buttons briefly.

— The new set temperature will be shown in the seven-segment display.

— If this is the desired Set Temperature the user can either:

– Briefly press the Set Temp button to turn off the Set Temp LED. — OR– Wait for approximately eight seconds when the freezer control panel

will return to normal operation.

4.4 – Over-Temperature Alarm• If the freezer compartment temperature is 10ºC warmer or colder than the setpoint

for five seconds then it will go into temperature alarm mode.

— The Over Temp light will go on (this is used for under temperature alarms as well).

— The freezer will make a double beep every 10 seconds.

— Situations which can affect the freezer’s ability to maintain a steady state or cooling rate include:

– The lid is ajar– The air vents are blocked– Addition of a large relatively warm mass– Power supply problems– Mechanical and/or electrical problems

4.4.1 – How to Silence the Audible Temperature Alarm

• The Over Temp light will always be lit when the cooler temperature is over or under the set temperature by more than 10ºC.

4.4.2 – To Postpone an Alarm

• When the audible alarm is sounding it can be postponed.

• Press the button beneath the Over Temp LED and the audible alarm will be turned off for 1 hour.


4.5 – Error Conditions• Certain conditions will cause an Error Code to be displayed on the seven-segment

display, and the Error LED will be lit.

— The error code will be of the form E ##, where ## is the error code.

— The error code will be displayed for about five seconds and then the display will show the chamber temperature. The Error LED will stay on.

— The error code can be recalled by briefly pressing the button under the Error LED. This will recall the error code for approximately 10 seconds.

— If button 2 is pressed and held for five seconds (three beeps) this will clear both the seven-segment display and the Error LED. However, if the error condition persists the error cycle will start over again.

4.6 – Locking the Control PanelTo Lock the Freezer Control Panel

• Press and hold buttons 1, 2 and 3 until the freezer beeps three times.

— Turn ON the ULT-25 by pressing and holding the I/O button.

4. Operation



5. Error CodesThese are displayed in the seven-segment display as E ##.

10

The free-piston Stirling engine is not maintaining a working temperature on the heat rejection fins. This could arise from blocked filters, blocked air pas-sages, unusually hot ambient temperatures (for example >45ºC), or a fan failure. Check air passages and clear any blockages for good air circulation. Remove from hot environments (car interiors, etc.).

40A component which monitors free-piston Stirling engine performance has failed. The free-piston Stirling engine cannot regulate itself. Please return for repair.

6. Maintenance6.1 – Caring for Your Freezer GasketThe temperature differential between ambient and the ultra-low interior can attract moisture near the gasket. For best results always wipe away moisture during openings to prevent ice accumulation. Do not use sharp instruments to scrape ice from the

surface.

6.2 – Air Intake FilterClean accumulated dust and dirt on the air intake filter every month. Pull the filter cover to the left as shown. Please note that it cannot be completely removed. Gently clean the filter with a vacuum cleaner. If there are stubborn residues use a soft brush to work them loose.

6.3 – Storage1. Turn off the power and allow the freezer to come to room temperature. 2. Dry the inside of the freezer compartment and clean any spills. 3. Disinfect with suitable sterilizing agent if the freezer has been used for biohazards.

6.4 – CleaningThe exterior surfaces of the ULT-25 can be cleaned as needed by using a soft cloth and mild detergent. Do not use solvent or harsh abrasive cleansers or pads.

5-7. Errors, Maintenance and Troubleshooting



8. Calibration GuideCalibrating the RTD with an Independent Temperature IndicatorThe Shuttle RTD is factory calibrated to display both setpoint and operating tempera-ture from a single internal RTD. In the event that you must re-calibrate the Shuttle to match the reading of an independent temperature recording device or stand-alone electronic thermometer, please follow this process.

1. Tools Required

• Flashlight or work light.

• Plastic screwdriver; do not use a metal screwdriver as this may short circuit the circuit board in the event of a slip.

• Independent temperature thermometer with sufficient lead wire to pass through the 1/8" access port and affix with duct tape to the vertical liner channel.

2. Precautions

• The Shuttle will be operating while you are calibrating the RTD.

• You MUST use a plastic screwdriver.

• Do NOT remove the front (control) of the Shuttle; there is no need. The control board can be accessed through the air filter.

3. Make Ready

• Insert your independent probe into the chamber with the leads passing through the 1/8" access port.

• With a piece of duct tape affix your indepen-dent probe next to the build-in RTD port on the interior front (see vertical strip that runs from the top to the bottom of the chamber; several oval holes indicate the best location). Do NOT cover the independent probe or thermocouple with the duct tape.

• Affix your independent probe adjacent to the oval holes WITHOUT CONTACTING THE PROBE WITH THE WALL; this will bring your independent probe into closest phys-ical proximity to the Shuttle control/display RTD which is located immediately behind the oval holes.

• Close the chamber lid and allow the interior chamber to pull down to (or return to) your setpoint temperature as displayed by the Shuttle display (not your independent probe display). This will stabilize the Shuttle and make ready for proper calibration.


4. Calibrate

• Slide open (do not remove) the air filter at the right front of cabinet. This moves the air filter out of the line of sight and provides a clear view of the calibration potentiometer on printed circuit board. — Caution: Use only a plastic screwdriver during this process.

• Locate the potentiometer of the printed circuit board. The potentiometer is an offwhite compo-nent with a Phillips head screw in the center. This is the calibration screw.

• There are 10 marks on the calibration device, 5 in each direction of zero (center). — Each mark represents approximately 1°C of offset. — This permits approximately a 5°C range in each direction.

• To calibrate, as follows: — Once stabilized, read your independent temperature display. — Read the Shuttle display. A. If the independent temperature display is warmer than the Shuttle display, turn the potentiometer CLOCKWISE in an approximate range to accommodate the offset. This will more closely align the control/display with your independent display. B. If the independent temperature display is colder than the Shuttle display, turn the potentiometer COUNTERCLOCKWISE in approximate range to accommodate the offset. This will more closely align the control/display with your indepenent display.

• Because of the thermal mass and control algorithms built into the system, the Shuttle controller/display will take approximately 15 seconds to react a change in potentiom-eter position either direction. Please wait for the Shuttle to make this adjustment.

• Repeat the process as required to more finely tune the Shuttle with your independent temperature display.

• Once you are satisfied with the calibration, return the air filter to its normally closed position.

• Store the plastic screwdriver in a safe place for additional calibration if needed.

5. Document Your Work

• Make a log entry into your operating manual (page 27) indicating the time, date and nature of this calibration.
